Question

A gas occupieda volume of 250 ccat 700 mm pressure at 25°C. What additional pressure is required to reduce
the gas volume to its volume at the same temperature?​

Answer 1

Answer:

A gas occupies a volume of 250 mL at 745 mm Hg and 25oC. What additional pressure is required to reduce the gas volume to 200mL at the same concentration? The additional pressure required is 931.25 - 745 = 186.25 mm.
